Yeah I remember that day your York locked up - still not sure what the deal was there. Did you ever tear into it to figure it out?

I didn't take it apart...I checked the oil level which was fine and the oil appeared to be in good condition. So, I fired it up and it seems to be working fine so - My guess is that it just ran for too long on the trail and then when filling up tires and decided to protest - I do need to verify that the pressure switch is working because with the tank, it shouldn't have to run for very long to either fill the tank or for the ARB's. You can't hear it running while driving on the trail and when it cycles it isn't really that noticeable either...A gauge in the cabin would help keep an eye on it.
